Besides the one time post, I have several that I keep adding too. Currently I have a choice to tell patrons if I have done that or not. I would prefer patrons (and non-patrons) to have that choice individually. I deal with a wide range of things.
A separate follow this post check box that counts checks similar to the like box would help me in knowing where to place my Patreon time. It would also focus my content where individual patrons want it focused.
Example of post I would add the follow button too:
